ChemInform Abstract: REACTION OF TETRATELLURIUM(2+) BIS(HEXAFLUOROARSENATE), TE4(ASF6)2, AND HEXATELLURIUM(2+) BIS(HEXAFLUOROARSENATE), TE6(ASF6)2, WITH TETRAFLUOROETHYLENE, THE PREPARATION OF BIS(PERFLUOROETHYL) MONO‐ AND DI‐TELLURIDE

AbstractFeste Telluriumarsenate (I) reagieren mit gasförmigem fluoriertem Äthylen zu den Verbindungen (II) und in geringerer Menge zu (III).

Reaction of tetratellurium(2+) bis(hexafluoroarsenate), Te4(AsF6)2, and hexatellurium(2+) bis(hexafluoroarsenate), Te6(AsF6)2, with tetrafluoroethylene. The preparation of bis(perfluoroethyl) mono- and di-telluride

Solid Te4(AsF6)2 and Te6(AsF6)2 react with tetrafluoroethylene at 100 °C to give (C2F5)2Tex(x= 1 or 2) and C4F9TeC2F5. In sulphur dioxide solution Te4(AsF6)2 and tetrafluoroethylene yield C2F5TeC3F6C(O)F in addition to products found for the neat reactions. C2F5SeTeC2F5 and C2F5TeHgTeC2F5 have also been prepared. Compounds were identified by their mass spectra, and by 19F n.m.r. in the case of the perfluoroalkyl tellurides.

Manual of Qualitative Analysis

OF the various manuals of Qualitative Analysis now in use, none is more deservedly popular than the work of Professor Galloway. Much of this success is doubtless due to the painstaking care with which the author has sought in successive editions to reduce the operations of Qualitative Analysis to a more methodical and systematic process. The present edition is in great part rewritten, and much new and original matter has been incorporated. More systematic methods for separating the alkaloids are given, together with many additional reactions for their individual discrimination. The processes for detecting the poisonous metals in presence of organic matters are also much improved. A description of Bunsen's neat and expeditious flame reactions is likewise a new feature in the book. The delicacy and certainty of these reactions ought undoubtedly to lead to their more general adoption in our laboratories; even if their application is found to be limited, the lesson in neatness and dexterity in working to be acquired in their performance would prove invaluable to the student.
